Strange behavior of the manjaro linux Gnome system

Startup -
Shutdown -

I recently installed Mandjaro linux Gnome and have never worked with linux before. So I’m a beginner and don’t understand it at all.
In general, I was fiddling around with the system, installing drivers, and then this blinking started when I turned it on and off (I attached a video of startup and shutdown on Google Drive), and the system stopped starting at all. Later I found a solution on some forum (I don’t remember where) but there I reinstalled the conflicting drivers through the terminal cntr + alt + f2. After that, the system started working but the blinking did not go away. And the system began to take an awfully long time to load, as did applications (although before everything was much faster). I don’t know what to do, help. Sorry for my English. I will be glad for any help.

I also began to notice that the system could simply freeze out of the blue.

Welcome to Manjaro! :smiling_face_with_three_hearts:

Have you already :mag: for your problem in the forum ? (Wisdom lies in asking → listening → reading :wink: )

For consideration:


For your description it is only possible to provide some generic pointers.

We have all been there

Breaking your system is part of learning your system - but you should do that at a slow pace.

A piece of advise - do not change system wide config unless you really know what you are doing - especially - do not follow advise on random internet blogs and youtube videos.

Such content may be outdated or does not apply to a Manjaro system.

When a Manjaro Linux system is installed - there is usually no need to install drivers

As Linux has buiilt-in kernel support for common hardware - only exceptions to that rule may be certain network devices which has been created for Windows ecosystem and thus do not have kernel support.

You can reset user configuration by copying the content (including hidden files (.dot files/folders)) of /etc/skel to your user’s home folder.

Everything outside your user’s homefolder will require superuser permissions - because Linux is secure by design - albeit not designed to prevent the user from breaking it.

Break your system at a slow pace. Let me write that down.
